IMPROVEMENT IN OIL-PRESSES.

1 Specification forming part of Letters Patent N o. 117,641, datedAugust l, 1871.

To all whom it may concer/n:

Be it known that I, AGUR JUDsoN, of Newark, in the county of Essex andState of New Jersey, have invented a new and valuable Improvement inFlaxseed-Oil Presses; and I do hereby declare that the following is afull, clear, and exact description of the construction and operationofthe same, reference being had to the annexed drawing making a part ofthis specication, and to the letters and gures of reference markedthereon.

Figure l of the drawing is a representation of a side elevation of myinvention. Fig. 2 is a similar view of opposite side. Fig. 3 is adetached sectional view of part of my invention. Fig. 4 is a perspectiveview.

This invention has relation to an improvement in oil-cake presses; andthe novelty consists in the construction and novel arrangement ofdevices hereinafter described, by means of which the plates holding thepressed cakes are allowed to fall one by one in a pile for the purposeof getting more plates and cakes in a press of given capacity. Also,(the plate and cake being in close contaet,) to retain the heatpreviously given to the meal until the same shall have been pressed.

In the accompanying drawing illustrating this invention, A representsthe top, A' the base, and A" the corner-posts of an upright rectangularpress-frame of sufficient capacity to hold a' number ofhorizontally-arranged plates, B, between which are placed the cakes,indicated in the drawing by b. O designates a verticallyworkingfollower, through the medium of which the oil-cakes are elevated totheir proper position and pressed between the head C' of the followerand the top of the press-frame. A slight notch is cut at each corner ofthe pans and follower-head, fitting them to the square cornerposts A",as shown clearly in Fig. 4. D indicates four vertical bars arranged atthe four corner-posts of the press-frame, and designed to slide up anddown within guide-cleats d. The upper ends of these bars are secured toradial arms d', the inner ends of which are attached to a collar, E,which slides vertically on the post F rising from the top of thepress-frame. G represents boxes secured to the inner sides of the postsA", and provided each with a number of horizontally-sliding bolts, g,formed with flaring or double-beveled slots or recesses g', throughwhich runs the bent iiange H projecting from the sides of the bars D.Each bolt is thrown forward or withdrawn by the bent part of said iiangepassing through the slot according as the so on. The ends ofthe boltsproject under and support the four corners of each pan, and bysimultaneously pressing the four connected bars D down each set of boltsis in order drawn back and the plates released. I designates a beveledtoothed rack secured to the sliding. collar E and operated upon by apawl, I', hinged or pivoted to the end of a lever, I", which isfulcrumed to the upper end of a standard, J, bolted to the top of thepress-frame. This lever is operated by a vertical rod, J', which runsthrough an eye, J", attached to any one ofthe posts A", and has itslower end bent horizontally to form a hand-piece and also a purchase forthe pivoted catch K. K' denotes a spring, which tends to keep the outerend of the lever I" elevated, and, consequently, the pawl I' out ofcontact with the rack I, it being thereby lowered. The end of the pawlis brought under each successive tooth of the rack by the alternateelevation and depression of the pawl I', operated through the medium ofthe rod J' and spring K'. L designates a bracket projecting from thestandard J toward the rack I, and holding a pivoted upright pawl or dog,L', having a double end, the formation of which makes an angular recess,into which the end of the pawl I' falls whenever the same is released. Aspring, M, tends to press the dog L' into contact with the rack, so thatit may support the same while the pawl I' is being lowered from onetooth to another. The force of the the spring K' is sufficient toovercome that of the spring M, and consequently the pawl I', when itfalls on the pawl L', throws the latter away from the rack, allowing itand the rods D to fall, supposing them to have been previously raised.The lower halves of the iianges H are of such a nature as to keep thebolts withdrawn, and when the bars D are 4elevated to their full extentall the bolts are out and the plates may The catch K, before referredto, is designed for the purpose of keeping the pawl I' in gear with therack I, so as to retain said rack in an elevated position when desired.It Will be observed that the pawl I' is of an elbow-form, the rear armacting as a Weight to throw the beveled or hook end toward the rack.`The object of the i pressure teierted byVY the follower is to Lpressthe oil from the cake and give it a proper form.

I claim as my inventionl. The arrangement ofthe bolts g, bent flan gesH, arms d', collarE, Aand rod F, applied to an oil-press, andconstructed substantially as and for the purpose specified.

2. The arrangement of the rack I, Weighted paWl I', lever I", spring K',and rod J with the bolts g and plates B, when constructed substantiallyas and for the purpose specified.

3. The notched or double-ended dog L' and spring M, arranged asspecified, in combination with the rack I and pawl I', as and for thepurpose described.

4. The arrangement and application of the latch K, in combination withthe rod J', pawl I', rake I, bolts g, and plates B, substantially as setforth.

In testimony that I claim the above I have hereunto subscribed my namein the presence Y:of tWo Witnesses."YY i 'i AGUR J UDSON.
